Hmmm...
What the hell did they mean by I-16bis?! La-5 1942? It looks more like I-180 that never saw combat, or I-185, but I don't remember where I-185s were tested in the frontline. Could be Karelia. If so - it can be a very rare rrecognition chart, there were only a few machines in one regiment!
What is I-17? Yak? Silouettes doesn't look correct...
It gives you an idea of a "reliability" of enemy plane recognition. Wonder how many "I-17s" Finnish pilots shot down.
Once I read an article about one of the last bomber raids to Finland in March, 1940. One DB-3 was shot down, and Soviet pilots said that it was attacked by "Spitfires". But even Hurries still were not delivered to Finland at that time! Grendel made some research and found some info about this fight from Finnish side. The plane was really new, but it was a G-50!
